Letters Patent N 96,006, dated October 19, 1869.

IMPROVED SNOW-PLOW.

The Schedule-referred to in these Letters Patent and making part of the same.

' To all whom it may concern Be it known that I, AUSTIN II. J ACKSON, of Bear Valley, county of Nevada, State of California, have invented an Improved Snow-Plow and Excavator;

and I do hereby declare the following description and accompanying drawings are sutticient to enable any person skilled in the art or science to which it most nearly appertains, to make and use my said invention or improvements without further invention or experiment The object of my invention is to provide an improved machine or plow for cleaning away the snow from roads amlgrailways, but more particularly for the latter purpose and 'It consists ot'a car, mounted upon wheels, so as to be moved along upon the rails in front of the locomotive. In the front portion of the car is placed a wheel, of a peculiar pattern, which, as the car is moved forward, draws in the snow and delivers it into a chamber in the middle of the car, in which a similar wheel is revolving in a transverse direction to the revolution of the front wheel. This latter wheel gathers the snow, and, by the force of its revolutions, hurls it through an opening in the side of the car, to a distance from the track.

The invention consists also of other devices, more fully explained in the following description, in which reference is made to the drawings accompanying this specification. and forming a part of the same, in which- Figure Us a perspective view.

Figure 2 is alongit-udinal vertical section.

The same letters refer to identical parts wherever they occur in each of the drawings.

A represents a car, which is intended to be placed upon wheels, for moving it upon a track or road.

This car can be made of any desired size, and is sheathed with plates of iron on its sides, and has its front end left open, so as to form a mouth, into which the snow is drawn.

In the front part of the car is a broad wheel, B, revolving upon axles bearing in the sides of the car, and of sullicient width to extend from side to side.

The arms or wings t.- of this wheel are of a peculiar shape, being thick at.- their bases, and extending about half their length on each side in a plane, the opposite planes converging toward each other.

The other half or point of the wings is made sliglrt- 1y convex, the two sides meeting at a point at their extreme ends.

The wheel shown in the drawings has but four wings, which may he suil'icient in practical use, but, if found necessary, a greater number may be em ployed.

-By reason of the peculiar construction of the wheel B, as above described, in connection with the peculiar concave shape of the bottom of the chamber D, withg of the raised ridge D, when the peculiar shape of the 'wings will allow it to slide over into the chamber E, or be thrown"into or upon the wheel in this chamber.

Inside the chamber E is a wheel, F, similar in construction to the wheel B, but bearing in crosst-imber G at one end, and in the. partition G at the opposite end, so as to revolve in a direction at right angles to the revolution of the wheel B.

The bottom of the chamberE is also made .concave.

The construction of the wheel 1 being of similar construction to the wheel B, as above stated, and revolving within the concave chamber, with one-thinl greater rapidity than the wheel B, the clogging of the. same by the snow is prevented, and it is thrown out of this chamber in an upward direction, and above the adjacent banks of sno and upon either side of the track, as may be desired.

In the sides of the car, opposite each other, are openings, H, which are made of the same width as the chamber E, and extend about two-thirds of the distance from the top to the bottom of the car.

These openings or apertures open into the chainher E, the bottom.of,.the chamber being on a regular curve from the lower' part of the opening on one side to the lower part of the opposite opening.

The snow, which is deposited into this chamber by the front wheel B, is immediately caught by the wheel F, and carried with it to the opening, and buried, by the centrifugal force of the wheel, through the opening, and toa distance from the car.

This wheel F is geared so that the direction of its revolutions can he changed so as to hurl the snow through the opening in either side of the car, dc-. sired, but the wheel B always revolves in the same direction.

The opening'which is not in use kept closed by a sliding door, I, which is moved in' ways along the side of the car by an extended rack, J, which passes over the top ofthe opening.

.A gear-wheel, K, operated by means of a crank from the platform L, engages with the rack J, so that the person who attends to the working of the .oAnLANo,

machine can, by simply turning the cranks, open or close either of the openings, as desired.

\Vhile the machine is discharging snow upon one side, the opening upon the opposite side is closed, thus allowing the snow to be throwntt') that side which is most convenient.

The top or deck of the car is extended a short distance in advance of the sides, and triangular wings, N, are hinged to the sides, so as to be opened out and stand at an angle to them, or closed up against the projecting deck in a plauc with them, as desired. I

An angular piece of metal, 0, is attached to the upper edges of the triangular wings N, to which are bolted or hinged levers a, and to the levers a, the levers b.

The levers I) extend the entire length of the decks, and project beyond them at the opposite end, passing through ways or passages so as to be concealed from sight, and also be guided in their movements when being operated.

By pushing these levers toward the front end of the car, the wings are thrown outward, so as to stand at an angle to the sides, thus forming a device for sloping the side of the snow-bank, to prevent its sliding in upon the car, or upon the track after the car has passed, and also to shape the bank so that the snow which is hurled through the openings will not strike the snow-bank.

When the car is mounted on wheels, it is raised a short distance above the track, and in order to clear the snow to a sutiicicnt depth, I attach to the front end ofthc. car, at the bottom, a short apron, which, falling down, rests upon the track, and elevates the snow within reach of the wings of the wheel B as the car advances.

The wheels B and F are driven by an engine carried at the rear of the car, while the car is pushed along by a locomotivc, and-when the wheels B and l are driven at their full speed, the snow will be thrown from thirty to forty feet from the track, being thrown also to a considerable height before fallin In place of the wheel B, a screw might be employed for taking up the snow and feeding it to the wheel F.

I do not wish to confine myself, in the construction to expel the snow inan upward of the wheels, to the particular former pattern of the wings before described, as various forms might be used which would answer the same purpose.

11am aware of the patent granted to U. \V. Tiernayi, dated March 16, 1869; and his mode of constructing his device will not, nor can it operate like the device described by me. His fan and screw revolve upon the same shaft, and at cqual speed, so that the tendency will be that the screw, from its inclined position to the snow, and also the fan, will become clogged when coming in contact with snow-banks or drifts, and from his construction there is no tendency direction. I have attempted to avoid all such objections by the peculiar construction of my snow-plow. 'Jlherctbrc,

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The construction and arrangementof a snowplow, in the manner and for the purpose herein doscribcd.

2. The peculiar construction of the wheel B, with its wings O enlarged at their base and convex sides, and combined with the concave bottom of the chamber I), in the manner and for the purpose herein described.

3. The combination of the wheel I with the concave-chamber, within which it revolves, in the manner and for the purpose herein described.

4. The combination of the wheels B and 1*,constructed as described, revolving at right angles to each other, and within thc concave chambers 1) and l), in the manner and for the purpose herein described.

5. The sliding doors I, with their extended racks J, operated by the gear-wheels K, substantially as above set forth.

G. The triangular wings N, secured to the sidcs of thc car,.and operated by means of lovers (1 and 1), substantially asand'thr the purpose herein described.

In witness whereof, I have hereunto set my hand and seal.
